Onkyo video issue
It's had a strange HDMI issue where the passthru device (currently a Dish box) will cut out briefly, or more recently go to a "scrambled"/noise (or "snow") screen briefly. It's been doing that for a few months I'd say. It's been a nuisance.
More recently (past couple of weeks) it seems to black out for several seconds at a time.
I am pretty sure it's the receiver but I haven't done any extensive troubleshooting as the blackouts happen more or less randomly.
I recalled there being some Onkyo HDMI issue but the only thing I can find is a network or sound issue that was prevalent up to 2012. (I'll note I bought my unit refurbished so it may have been made in 2012).
Has anyone here had a similar issue and had it fixed (for free)?
